COMBINED CARBONIC-ACID RECEIVER AND PRESSURE-REGULATING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 613,810, dated November8, 1898.

Application filed August 16, 1897. Serial No. 648,450. (No model.)

To aZZ whom it may concern.-

Be it known that I, RUDOLPH WINNIKES, a subject of the German Emperor,residing at Berlin, Germany, have invented a certain new and usefulImproved Combined Carbonic- Acid Receiver and Pressure-RegulatingMechanism, of which the following is afull, clear, and exactdescription.

The present invention consists of a combined carbonic-acid receiver andpressureregulating valve for use in retailing liquors, such as beer andthe like.

The invention consists in the details of construction hereinafter setforth, and particularly pointed out in the claims. 7

In order to render the present specification more easilyintelligible,reference is had to the accompanying drawings, in which similar lettersof reference denote similar parts throughout the several views.

Figure 1 is a central vertical section through the device; Fig. 2, a topplan of the same; Fig. 3, a horizontal section on line A B of Fig. 1;Fig. 4, a similar section on line 0 D of Fig. 1; Fig. 5, a section online E F of Fig. 1; Fig. 6, a section on line G H, Fig. 1; and Fig. 7, aside elevation, partly in section, of a modified form of the device.

Referring to Figs. 1 to 6, the device consists of a bell orreceiver,which is divided by means of a horizontal partition into anupper or carbonic-acid-containing receiver A and a lower chamber B,Whichcontains the pressure-regulating mechanism. The partition separating thechambersis provided with a strength eningrib y, in which is mounted thetubular downward extension 6, forming a channel through which thecarbonic acid may pass to the lower chamber B. The lower end of the tube6 is covered or loosely inclosed in an inverted thimble-piece g, havingtherein a plate 72, adapted to close against the lower open end of thesaid tube. This thimble rests on the free end of a lever i,.pivoted in abifurcated bearingpiece f, screw threaded into the strengthening part yof the partition. The opposite end of the said lever is pivoted to thelugs n of a nozzle having a boring n said nozzle being suitably fixed ina membrane is, mounted at the bottom of the chamber B and partitioningthis chamber off from the lower chamber 0. The lower chamber 0 isprovided with a tubular downwardly-extendin g mouthpiece having alateral opening 4; and being interiorly screw-threaded to receive a nut19, having upwardly and downwardly extending tubular extensions andbeing provided with lateral orifices 10, Fig. 4., into which a tool maybe inserted through the opening 4;, so that the position of the saidnutin the throat-piece may be varied. The upper surface of the nut formsthe bearing-surface for the spring 0, which bears against a metal washeron the membrane and has the tendency to push said membrane upwardly.Thus if the position of the nut 13 is altered the tension with which thespring 0 bears against the membrane may be regulated. Thedownwardlyextending end of the nozzle, having boring n is provided witha flexible tubular extension q, consisting of two parts,which are heldtogether by means of an inserted glass tube q, the lower end of saidflexible tube openinginto an upper chamber formed in the housing of thecock D.

The device is screwed into the bung, plunglug-siphon, or tap,which is inconnection with the cask. Itsoperation Will be obvious. As soon asliquor is drawn off the pressure underneath the membrane will decreaseand carterior of the cask, the constant pressure in the cask beingregulated according to the adjustment of the spring 0.

The dimensions of the glass and flexible tubes are so chosen that incase of excessive pressure the latter will slip off the glass tube andthus form a reliable safety-valve.

The top of the receiver A is provided with a valve device through whichcarbonic acid maybe supplied to the said'receiver. At the upper part ofthe housing A is provided a nozzle having interior and exterior threads,into the former of which a plugr is screwed, while the latter is coveredby means of a nut a. The lower part of the plug 0 is hollowed out toreceive a second plug d, having therethrough an orifice t, said plugforming with its upper surface a seat for a free-lying valveplate 0,having formed in its under surface channels 3 s, Fig. 6. The main plug ris provided with a central vertical channel a and with two depressions zz, by means of which the said plug may be screwed into the neck of thereceiver. When carbonic acid is to be supplied to the receiver A, thenut a is unscrewed and the mouthpiece of the carbonicacid flask screwedonto the neck of the receiver. The carbonic acid will flow through thechannel it onto the valve-plate 0 underneath the same through thechannels .5 into the receiver A, and when the flask is detached from theneck or nozzle of the receiver the valve-plate 0 will be closed by theinterior pressure against the plug 0', thus preventing the escape of thecarbonic acid from the receiver.

In the modification shown at Fi 7 instead of the orifice n alaterally-formed channel a a is provided. The device is otherwise thesame as that previously described.

The cock D may be employed to close the apparatus when it is shiftedfrom one cask to the other or when it is charged and not in use.

I claim as my invention 1. The combination of a carbonic-acid receiverand a chamber as specifiedand partition between the two, a tubularoutlet 6 from the receiver to the chamber, having inverted thimble-pieceto inclose same loosely, a lever z and means for suspending the samepivotally from the partition-wall between the receiver and chamber,pivotal connection between the end of said lever and adownwardlyextending nozzle, a membrane closing the bottom of saidchamber and means for at taching said nozzle to the membrane, a chamber0 below said membrane having throatpiece with lateral opening 1) anadjustable nut in said throat-piece accessible through said opening, aspring arranged between said nut and a plate on the membrane, a flexibletube connection from the membrane-nozzle, said tube connection being intwo parts, a glass tube to connect said flexible tube parts a cock toclose said throat-piece and means for securing the whole to the cask orthe like substantially as described.

2. The combination of a carbonic-acid receiver, a valve-chamberthereunder and a partition between the two, a membrane underneath andclosing said chamber, a tubular downwardly-extending outlet to saidpartition an inverted thimble-piece to loosely inclose said outlet alever device in connection with the membrane to operate said thimble, achamber below the membrane having therein an adjustable membrane-spring,a cock below said spring and an outlet from the valve chamber to saidcook, a carbonic-acid inlet to the receiver consisting of a plug 0'having mounted therein a second plug d an orificet in said second plug avalve-plate thereover having channels 3 in its under surface, and anorifice above said Valve-plate through the plug 0' and a cap-nut Ct toinclose the whole substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

RUDOLPH WINNIKES.
